Key Features
- 28-position dual-row layout at 0.050 inch pitch supports high-density signal routing in approximately 18 mm connector length
- Tiger Eye contact technology provides consistent wiping action and reliable mating across multiple connect-disconnect cycles
- Footprint-mount (FM) SMT termination style enables direct solder reflow attachment compatible with standard pick-and-place assembly
Applications
TFC-114-02-FM-D-A is used on embedded processor expansion boards and FPGA daughter cards where 28 signals must be interconnected between boards at 0.050 inch pitch to conserve PCB real estate. Test fixture and automated test equipment (ATE) designers use it to build modular probe cards that accept interchangeable device-under-test adapter boards with 28-pin interfaces. Industrial communication module manufacturers use it for field-replaceable interface cards in compact DIN rail-mounted controllers where connector height under 5 mm is required.

Frequently Asked Questions
How many positions does TFC-114-02-FM-D-A provide, and how does the dual-row arrangement affect routing density?
TFC-114-02-FM-D-A provides 28 positions arranged in 2 rows of 14 contacts each at 0.050 inch (1.27 mm) pitch, fitting all 28 connections into a connector body approximately 18 mm long. The dual-row arrangement doubles routing density compared to a single-row connector of the same length, reducing the PCB edge or midboard area consumed by inter-board signal connectors in embedded module and mezzanine card designs.
What does the FM (Footprint Mount) designation in TFC-114-02-FM-D-A indicate about the termination style?
The FM designation indicates Footprint Mount termination, meaning the connector leads are configured to surface-mount solder directly onto PCB pads using standard reflow soldering at peak temperatures of 260 °C. This SMT termination allows TFC-114-02-FM-D-A to be placed by automated pick-and-place equipment alongside other SMT components, eliminating the manual insertion step required by through-hole connectors and reducing assembly cost per board.
In which board-level interconnect scenarios would a designer select TFC-114-02-FM-D-A over a 28-pin ribbon cable assembly?
TFC-114-02-FM-D-A is preferred over a ribbon cable when a rigid board-to-board connection is acceptable and the boards are always separated by a fixed 0.050 inch pitch mating distance. It eliminates cable routing over 28 wires, reduces assembly time by eliminating cable crimping, and enables a connection height under 5 mm between the two boards — making it the right choice for stacked PCB modules in rack-mount or embedded systems where cable slack and harness routing overhead would otherwise add 10-20 mm to the assembly envelope.
How does TFC-114-02-FM-D-A compare in position count to other SAMTEC TFC series connectors and when is 28 positions the right choice?
Within the SAMTEC TFC series, position counts range from 8 to over 80 positions at 0.050 inch pitch; TFC-114-02-FM-D-A at 28 positions sits in the mid-range suitable for general-purpose interface buses such as a 16-bit data bus plus address and control lines totaling 28 signals. Compared to 26-position (TFC-113) or 32-position alternatives, the 28-pin count matches standard bus widths used in embedded microcontroller peripherals, Ethernet PHY interfaces, and LCD display controllers, reducing unused pins and keeping connector cost minimal.
